Praise for Understanding Context
Foreword
Preface
The Practical Bit
Who Should Read This Book?
So This Book Teaches Methods for Designing Context?
Why Information Architecture?
What Will You Learn from This Book?
A Tour Through the Book’s Six Parts
The Personal Bit
Acknowledgments
I. The Context Problem
1. Everything, Yet Something
Birds in Trees, Words in Books
Scenario: Andrew Goes to the Airport
Breaking It Down
2. A Growing Challenge
Early Disruptions
The Role of the Web
Case Study: Facebook Beacon
3. Environments, Elements, and Information
A Wall and a Field
A Conventional Definition of Context
A New, Working Definition of Context
Modes of Information
Starting from the Bottom
II. Physical Information
4. Perception, Cognition, and Affordance
Information of a Different Sort
A Mainstream View of Cognition
Embodied Cognition: An Alternative View
Action and the Perceptual System
Information Pickup
Affordance
Affordance is a revolutionary idea
Affordances are value-neutral
Perception of affordance information comes first; our ideas about it come later
Affordances exist in the environment whether they are perceived or not
Affordances are there, whether they are perceived accurately or not
Affording information is always in a context of other information
Affordances are learned
Directly Perceived versus Indirectly Meaningful
Soft Assembly
“Satisficing”
Umwelts
5. Attention, Control, and Learning
A Spectrum of Conscious Attention
Environmental Control
Memory, and Learning the Environment
What is Memory?
Types of Memory
An Embodied Perspective on Memory
Learning and Remembering versus Memory
Learning and Remembering are Entangled with Environment
Environment, and Explicit versus Implicit Memory
What Does All This Mean for Design?
6. The Elements of the Environment
Invariants
Examples of Invariants
Variants
Compound Invariants
Invariants Are Not Only About Affordance
